Originally this was posted in the Q45 section, but I realized with sudden clarity it was meant to be placed here....
Well, it's been a nightmare. I got the car thinking it would be an easy motor swap and have a cool project. After dealing with the horrible swap that CraigsToyz did on the vehicle, I have redone practicaly after part of the swap. I did leave the steering rack Craig put in there...
Anyways, I've started to draw to a conclusion. The details are she’s an 85 RX7 with a 96 VH45. I'm currently in the progress of establishing the wiring. There was no CEL, OBD2 port or knock sensor connected. I've got the FSM and the pin out established, what I am hoping is that someone can tell me where about they split from the harness? I'm hoping to be able to use as much of the OEM wiring as possible. A lot of things are re-wrapped, so I'm hoping if I can narrow it down I won’t need to unravel the entire harness.
Secondly, here are some pictures.
The car:
The reason the motor was blown:
There was some pretty serious wear on the cylinder walls, and at least a .010 over would have been required. The crank had some serious wear on it, and most likely I would have needed the .12 undersized bearing that Infiniti offers. But with pistons being as expensive as they are, I opted to go with a junk yard. After much labor and cleaning, and painting, I wound up with this....
Here are some examples of CraigToyz fine work...
The tranny mounts were welded in, not only were they welded OVER the bolts holding the mount in, they were also welded TO the bolts (that weren't even tight). Guess how much fun the transmission was to cut out? And how many blades I chewed through on the reciprocating saw? 4. Because of the way it was welded up, there was no clean angle to cut. I had to cut away sections at a time, so I nicked the tip quite a bit and either bent or shattered blades. The best weld on the damn car was the bolt that was welded to the rear of the tranny mount.
The other side, which had the muffler welded on to it as well.
The headers/exhaust. Yes, the exhaust actually is the flex-tube aluminum piping, welded right to the header collector and muffler. Not to mention the exhaust was solidly welded to the car, and the the bolts as well were welded to their brackets.
The original motor mounts were made out of pretty thin metal, and not reinforced at all. A simple "L" that was welded on at the very bottom, they were bending needless to say. Not to mention, the motor mounts weren’t even bolting to the mounts. So I removed all of the welds, and created new mounts that were 1/4" steel, on the sides and 1/2" on the top. I did reuse Craig's metal because he did already get the angle for the engine mounts to cradle in. Here are my new mounts...
Here's the engine bay as I'm sanding away all of the oxidation Craig painted over,
And here it is painted
This is me sitting the motor in there to line up the holes for my new mounts
I lined it all up, did some fab work/drilling and here is how she sits now.
As of right now, I need to finish created a tranny mount and I am waiting for all my mandrel pipes to come in from summit so I can make some log style headers, that are...dare I say...flippable
I've got the entire set up designed so that if I decide to boost, I can flip the headers and re-use my entire exhaust set up. I'm hoping to have enough room to slide my headers in without completely removing the motor, but I doubt it will happen.
On the list as well, is to create a way to hold the radiator. Craig was using a plate that was held on by a bolt (with no nuts) and some thick wire, looked like that coated wire coat hanger.
